Also going out on a bit of a limb here.
If I ask my self where are the stresses from a cornering load in the back, I would say, 1 panhard rod, 2, torsion load in arms (maybe, I would assume the pan hard rod would try to remove this), 3 lateral spring load.
Please feel free to argue with me :y:
After a bit more thinking (yah work :thumbsup:) IMO it would be hard to actuality brace the spring perches them selves (Like easy enough braces in the front) as they are pretty much level with the floor of the boot. Anybody keen on some tension string and video?
